MASONS TOOL.

SPECIFICATION forming part of Letters Patent No. 491,997, dated February21, 1893.

Application filed May 10, 1892. Serial No. 432,529. (No model.)

To aZZ whom it may concern.-

Be it known that I, JAMES GILMOUR FAULDS, a subject of the Queen ofGreat Britain, and a resident of the city of Glasgow, Lanarkshire,Scotland, have invented certain new and useful Improvements in MasonsTools, of which the followingis a specification.

This invention relates to masonschisels and liketools and it has for itsobject to make a single handle with one or more interchange able bits,serve insteadof' a number of tools, as at present.

In order that my said invention may be properly understood, I havehereunto appended an explanatory sheet of drawings, whereon Figure 1shows a drafting tool with the improvements. Fig. 2 shows a largerboster than Fig. 1. Fig. 3 shows. the manner of fitting the bit inplace. Fig. 4 is a perspective view of a bit and Fig. 5 is an end view.

In carrying out my invention, I make the boster,- drafting or otherchisel or the like with the usual metallic shaft or handle a. which isbroadened or flattened out and tapered at its lower end a. The flattenedout part is made with a groove or recess 1). Into the recess orgroove 1) is fitted a bit 0, of which there may be any desired number tosuit the different classes of work. End walls cl, d are provided at theends of the recess for the purpose of preventing the bit a movinglaterally when being used. The bits 0, are preferable cut at each side,as shown in dotted lines at c Fig. 4, so as to fit into the recesses.The bits 0 may be made with a number of teeth 0' like a comb, so as todo a greater amount of work than with the usual arrangement of chisel,which has but a single broad tooth or cutting edge. The bits 0 may bediamond shape in end View as shown at Figs. 4 and 5 with both sidestapered the upper side being made with but a single broad tooth orcutting edge whilst the lower side has a number of narrow teeth a. A bitmade in this shape is reversible. The reversible bit shown has teeth onboth sides.

In Fig. 3 the tapered bit is merely driven A into place which is themode I prefer, as the bit is not so liable to shake about when oncejammed tightly in place. To preserve the upper cutting edgeI prefer topartially fill up the recess with soft-metal such as lead or soft copperor copper wire h. When the bit is driven in the soft metal helps to holdit firmly and securely in place. time, be taken out and sharpened. Theteeth of the bits are, preferably, stamped out ofthe metal. They mayhowever be filed out.

With this invention, the trouble,incidental to masons carrying aboutwith them a kit of tools, is obviated, as all that is now required isfor the masons to have but a single handle or shaft or at most two orthree and a number of bits, suitable for the different classes of work,which are easily carried about, as they are small.

Having now fully described my invention, what I claim, and desire tosecure by Letters Patent, is'

1. In combination,the toolhandle having a broadened lower end providedwith a socket and end walls d and the diamond shaped reversible toolhaving two cutting edges, said tool being cut away at its corner edges eon both sides, substantially as described.

2. In combination, the tool handle havinga socket in its lower end thefilling of yielding metal in said socket and the diamond shapedreversible tool adapted to said socket and to be held by contact withsaid metal and socket, substantially as described.

3. In combination, the tool handle having a socket in its lower end, thefilling of yielding metal consisting of wire and the tool of diamondshape adapted to be driven into the said socket, substantially asdescribed.

In witness whereof I have hereunto signed my name at Glasgow, Scotland,this 20th day of April, 1892.
